No Caves

New in this version:

• Nice QoL update!
• Made old cave distribution feel more like pre1.18 rather than just disabling the new cave generation.
  • I looked at how the carver caves changed from 1.17 to 1.18 and it is pretty different, but there were a lot of changes not accounting for the vast difference in terrain height.
  • This means lava ravines exist again! Woohoo!
  • This also means you'll get nice caves that you can get lost in again.
  • Finally, surface caves will also be more common.
• Reduced water caves
  • Not really feasible to fully remove them for several reasons, but this should make the underground less aquatic. Friendly reminder that these spawn near rivers and oceans.
